Inverse Error Function The inverse error function is defined as erf -1(x), such that erf(erf -1(x)) = erf -1(erf(x)) = x. Here erf(x)=2√πx∫0e−t2dt is the error function. Tips Calling erfinv for a number that is not a symbolic object invokes the MATLAB® erfinv fu...
erfinv(erf(x))=x. Tips For expressions of the formerfinv(1-x), use the complementary inverse error functionerfcinvinstead. This substitution maintains accuracy. Whenxis close to1, then1 - xis a small number and may be rounded down to0. Instead, replaceerfinv(1-x)witherfcinv(x). ...
This MATLAB function returns the value of the Inverse Complementary Error Function for each element of x.
This MATLAB function returns the input argument of the Q function for which the output value of the Q function is y.
err_bs = 3.7705e-06 res_bs = norm(A*z-b) res_bs = 3.7080e-15 The backslash calculation is quicker and has less residual error by several orders of magnitude. The fact thaterr_invanderr_bsare both on the order of1e-6simply reflects the condition number of the matrix. ...

The acosh function fully supports tall arrays. For more information, see Tall Arrays. C/C++ Code Generation Generate C and C++ code using MATLAB® Coder™. Usage notes and limitations: Generates an error during simulation and returns NaN in generated code when the input value x is real, ...
In order to reproduce the asymptotic behavior of the inverse Langevin function, a rational function is considered only in the asymptotic zone keeping C^1 continuity with the cubic splines. We include customizable Matlab codes to create the spline coefficients, to evaluate the function, and to ...
